| dc.description | Cascade decays of heavy flavor hadrons to states with neutral kaons are discussed as an instrument for detailed studies of the heavy hadron properties. For neutral flavored mesons the well-known kaon oscillations provide a unique experimental possibility of relating lighter/heavier eigenstate masses to (approximate) even/odd eigenstate CP-parities and to longer/shorter eigenstate lifetimes. As a result, they allow to eliminate sign ambiguities of CP-violating parameters and, therefore, to check the Standard Model (or to find New Physics). Specifically for charmed hadrons, both neutral/charged mesons and baryons, the secondary kaon oscillations permit unambiguous separation of Cabibbo-allowed and doubly-suppressed decay amplitudes, including measurement of their relative phases. For neutral $D$-meson decays the kaon oscillations can also discriminate, again unambiguously, between effects of $D$-meson mixing and interference of suppressed/allowed amplitudes. Another problem discussed is the influence of kaon CP-violation on the amplitude structure and on phenomenology of CP-violation in heavy hadron decays. | |
